The side of a rhombus is 15 centimeters long, and the length of its longer diagonal is 24.6 centimeters. Find the area.
The diagonals in a rhombus right-bisect each other, giving you 4 identical right-angled triangles
look at one of them, the hypotenuse would be 15 and the other side is 12.3 , half the diagonal given.
Can you find the missing side using Pythagoras?
Find the area of one of the triangles , then multiply by 4
211.6 units squared
